Abstract
Water samples from standard depths (0-5ohn) around Andamans collected during December, 1988 to January, 1989 were analysed for various hydrographic parameters and nutrients. A study o f hydrographic parameters showed that the thickness of the surface mixed layer was less around North Andaman and eastern side of Little Andaman. The distribution of nutrients showed that the surface concentrations of silicate and phosphate were high and comparable to those in other world oceans. However, the deeper values were less. But it is striking to note that the NO,N concentration in the surface layers (0-5Om) was very low and almost undetectable. This is well in accordance with the reported low primary productivity of Andaman waters. The lower inorganic nitrogen concentration in the surface may be due to the slow process of regeneration of nitrogenous matter and absence of adequate supply of inorganic nitrogen from the deeper layers due to limited mixing.
